Our group is primarily a surface chemistry and physics group which focuses on the use of high-powered pulsed lasers, low-energy electron scattering, micro-plasmas, mass spectrometry and ultrahigh vacuum surface science techniques. We use this "tool-set" as well as some scattering theory to unravel the details of non-thermal processes occurring under a variety of non-equilibrium conditions. Our group is based upon an interdisciplinary approach and thus our research programs span the realm of fundamental investigations in molecular physics, surface physics and chemistry, bio-physics, bio-polymer formation under pre-biotic conditions as well as working in applied areas of relevance to analytical technique developments, atmospheric chemistry, catalysis and molecular hydrogen generation.

Dr. Ng is the Love Family Professor in the School of Chemical & Biomolecular Engineering and the School of Earth & Atmospheric Sciences at the Georgia Institute of Technology. She earned her Ph.D. in Chemical Engineering from the California Institute of Technology and was a postdoctoral scientist at Aerodyne Research Inc.

Dr. Ng’s research focuses on the understanding of the chemical mechanisms of aerosol formation and composition, as well as their health effects. Her group combines laboratory chamber studies and ambient field measurements to study aerosols and air quality using advanced mass spectrometry techniques. Dr. Ng leads the establishment of the first, high time-resolution, long-term aerosol measurement network in the U.S.: Atmospheric Science and Chemistry mEasurement NeTwork (ASCENT), for characterization of aerosol chemical composition and physical properties, and their impacts on climate, human health, and ecosystems.
